Re: [EnergyPlus_Support] Fancoil on/off

[Fred Buhl <wfbuhl@xxxxxxx>]

Fan coil unit: the fan is always on when the unit is scheduled on.

Unit Ventilator: on when scheduled on AND there is a load.

So it looks like the Unit Ventilator does what you want.

Which one of these is correct?  From what I can tell the fan of the fancoil always runs if it is scheduled to be available even if there is no load on the unit.
